Malposition risk and placenta placement?

Hi ladies Smile

I've been kinda quiet, but I need some of your collective wisdom.

Things are going great with my OB - she is VBAC friendly and has so far had a 100% success rate for VBAC attempts (has only been in practice 2 years).

Everything looks good on the anatomy ultrasound, I have a marginal previa, but it only has to move 0.5 inches between now (20+6) and delivery, which shouldnt be an issue at all.

She's going to let me monitor sugars instead of doing the glucose test (yay!)

And she reassured me that if she isnt the one on call when I go into labor that she will leave instructions to BE CALLED and will come in (not all of her call partners are as VBAC friendly as she is)

My question is this: I ended up with a c-section due to several things (GDM, talked into induction at 40 weeks with a Bishop score of 0, etc) - but I think the main one was that Brayden was OP and had his head in such a position that he would've injured his neck trying to actually come out (molding looked like an OA baby). He NEVER fully engaged and I only made it to 8.

Best we can figure, he may have been OP due to my anterior placenta last time. I did all the right things - spinning babies, webster-trained chiro, etc and labored w/o epi for 19 hours before giving in to anesthesia (was on HIGH DOSE pit) so I could change positions, etc

I am concerned this time b/c the ultrasound showed another anterior placenta. not only is it anterior, it's low, so it probably implanted over the scar (apparantly this is one of those nondisclosed c-section risks). Does anybody know or have info on the relationship between anterior placentas and malposition? I've started adjustments with my chiro again and will do everything I know to encourage good positioning, but Im just worried.

any advice?

Thanks!

Anecdotally, you'll probably find about as many women whose OP babies faced away from their placentas as faced them, and the same with women with OA babies. My daughter had an anterior placenta, she was a perfect OA. My son's placenta was at the top, he was another perfect OA until shortly before my c-section & I attribute that to my own poor position, lying in bed with an epidural.

There was a study in 1994, Gardberg & Tuppurainen, that purported to have linked OP position with an anterior placenta. Here's the deal: they did sonograms on 325 pregnant women who were beyond 36 weeks but not in labor. 11.6% of those women, or 38 of them with rounding up, had a baby in the OP position, and of those 38 a "majority" had an anterior placenta. I can't find out what the exact number is without buying the article from a medical publication. Even so, there was no information provided about how many of the women with an OA baby had anterior placentas. And 38 is such a tiny number to draw a statistic from that I find it laughable that the study was even published! And finally, we all know that babies move around, so the fact that a baby was OP when the sonogram was done doesn't mean the baby would be OP during labor, or vice versa. It might have been a better study had the sonograms been done in early labor. So what I'm saying, in a nutshell, is that that study was worthless & you don't need to worry about your baby being OP simply because you have an anterior placenta. Blum 3

Both of my boys were OA. One placenta was posterior and one was anterior.

Thanks. I think my anxiety about the whole thing is what I need to work on the most.

I swear it's almost like PTSD. I had anxiety last time too, but it was
More Of a first time mom thing and a knowing too much thing (I'm a physician).
